There are several different medications that can help to prevent the frequency of HAE attacks, and treat symptoms should they occur.

Hereditary angioedema (HAE) causes swelling and discomfort of the skin, gastrointestinal tract, and upper airway. Swelling that occurs in your upper airway can be life threatening.

Some may mistake allergic swelling for HAE swelling. These conditions have distinct symptoms, treatments, and risks. As a result, it is important to clarify the diagnosis as a first step

before getting treatment.

Doctors can differentiate HAE attacks from other causes of swelling through careful review of symptoms and their timing as well as blood sample analysis.

In this article, we detail the different treatment options for HAE.

While there’s no cure for HAE, there are many ways to prevent or subdue swelling attacks. In recent years, eight new prescription medications have become available in the United States to

help you manage HAE.

These medications treat HAE differently, and their administration and dosing recommendations vary. Four of the medications prevent symptoms, and four treat acute HAE symptoms. Children can

use some of these medications, but a few are only for adolescents and adults.

Management plans for HAE vary from person to person. Your doctor can help you determine the best course of treatment for you. Your plan may involve taking preventive medications or taking

medications at the first sign of an HAE attack.

It’s not always possible to prevent an HAE attack, but by knowing common triggers, your can work with your doctor to create a prophylaxis plan to reduce the chances of an attack during

exposure to triggers.

Talk with your doctor about managing these triggers and seeking short-term treatments for situations like dental work, surgery, and pregnancy.

The FDA approves the following drugs for the treatment of HAE.

Doctors can administer several medications to stop acute attacks. These include C1 esterase inhibitors (Berinert and Ruconest), Ecallantide (Kalbitor), and Icatibant injections (Firazyr).

Specific HAE triggers can vary between cases. However, the most common triggers are emotional stress, physical stress, and dental procedures.
